I saw this as part of a compilation of gay-themed shorts entitled "Boys Briefs 2," (advertised as stories about "gay first lust") and wasn't prepared for the dark, disturbing tale that unfolds here. "Touch" gives us a fractured narrative about a young teen who was imprisoned and sexually & physically abused by his captor for quite some time. How much isn't really clear, though the occasional flashbacks suggest that the abuser was a man who had been living with the boy and his mother.
What makes this short film so unsettling is that it is completely from the POV of the victim - now freed and living with foster parents. This young man now so identifies with his former captor that he cannot differentiate between real love & affection and being beaten - the two have been so thoroughly entwined in his traumatized head that he is set on a course of constant self-abasement to find his former "lover" again - or some equivalent from strangers.
The point the film makes is psychologically acute, and no less unnerving for being so.
